Sure, week seven is a strange week to start. But what makes fantasy football great is the week-to-week fluctuations between players. How different owners perceive player performance in a given week could create interesting buy-low or sell-high opportunities for your fantasy team.

Look at Braylon Edwards. For five weeks, he was fantasy kryptonite. He had no trade value because of his abysmal early season performance, but after a 154 yard performance, how much do you discount his non-productivity early?

Edwards and Randy Moss have virtually the same amount of fantasy points through five games, but what is either player's true value? Is Edwards going to build on his Monday night performance, or will Randy Moss rebound late in the season to be the fantasy stud he has been throughout most of his career?

Then there are injuries to guys like Tony Romo, Joseph Addai, and Willie Parker. Obviously if you need to win immediately, trading for them wouldn't be prudent, but how much do their injuries affect their value?

Finally, there's the question of who is number one. Does LaDainian Tomlinson hold onto his preseason top ranking? Or have his injuries paved the way for Marion Barber, Adrian Peterson, Frank Gore, or even Drew Brees or Larry Fitzgerald to man the top spot?

Let me warn you that these rankings will change every week. Just because a guy is number one now doesn't mean he will stay there all season. But if you had to draft today, or if you're looking to cross-rank players, here is my fantasy fifty based on what I've seen this season, and based on how I believe these players will perform down the stretch.

1. LaDainian Tomlinson, SD, RB - Says he's healthy, and while his production hasn't been all there, no one has taken the throne from him yet.

2. Adrian Peterson, MIN, RB - Hasn't shown it all just yet, but his upside is immense.

3. Clinton Portis, WAS, RB - Feature back in a good offense. 100+ yards in three straight, and he scores touchdowns.

4. Frank Gore, SF, RB - Very consistent. 49ers know that their only chance to win is a heavy dose of Gore.

5. Marion Barber, DAL, RB - Will injuries to Romo and Jones help or hurt him? It's hard to tell, but you know that he will get a heavy load this week.

6. Brian Westbrook, PHI, RB - If he's healthy, he's higher than this, but it's a weekly struggle to keep him on the field.

42. Calvin Johnson, WR, DET – Because what else is Detroit going to do? Shaun McDonald and Mike Furrey could take some pressure off Megatron, but there will be will post some duds.

43. Larry Johnson, RB, KC – Suspended for week 7. Other than that, he’s a poor man’s version of Brandon Jacobs spliced with Michael Turner. Matchups play, but a good one when he’s on the field.

44. Antonio Gates, TE, SD – Getting healthier, and still scoring touchdowns. 4 TDs in 6 games this season make up for just 252 yards.

45. Thomas Jones, RB, NYJ – 3 touchdowns last game a good start, but yardage has not come easily.

46. Ryan Grant, RB, GB – He got 33 carries last week. Only 90 yards, but the Packers will want to give Grant every chance to live up to his new contract.

47. Earnest Graham, RB, TB – Warrick Dunn is a major concern for Graham owners, but Bucs trust him in the red zone, and he’s been able to break three runs of 45 yards or more.

48. Lee Evans, WR, BUF – Poor man’s Greg Jennings usually good for a big play downfield. Scored in last 2 games.

49. Dwayne Bowe, WR, KC – Usually a consistent option and the bona fide #1 option in Kansas City. Would like him more if Huard were starting.

50. Laveranues Coles, WR, NYJ – He and Cotchery are pretty equal in terms of value, but slight edge to slightly more explosive Coles.

Five to watch

1. Devin Hester, WR, CHI – With Brandon Lloyd out, Hester has stepped in and performed pretty well. Bears give him every chance to break open the big play, so if you’re looking for receiver help, he’s a decent option.

2. Ryan Torain, RB, DEN – If you’re scraping the barrel at runningback, Torain has as high an upside as anyone you can grab. Rookie turned heads in Broncos camp, and will vie for carries starting 11/2.

3. Dominic Rhodes, RB, IND – Chances are, he’s already gone in your league, but if not, Rhodes is a good option as the feature back in a Manning-led offense for a couple weeks.

4. Kevin Walter, WR, HOU – Somehow available in many leagues still. Matt Schaub is a solid QB, Slaton can run the ball, and Andre Johnson can take pressure off him on the other side. Walter has 3 TDs on the year and is coming off a 98 yard game. Plus, if Andre Johnson ever misses time, he’s gold.

5. Jamaal Charles, RB, KC – Larry Johnson should only miss one week, and Kolby Smith might get the start this week, but look for Charles to get more touches. Tennessee defense should prevent a big game from any Chief, but if Charles plays well, he could challenge the headache that is Larry Johnson.
